Norelco SH71/52 Replacement Shaving Heads 3-Pack — Self-Sharpening SteelPrecision Blades for Series 5000 (angular) & 7000

These are genuine Philips Norelco SH71/52 replacement shaving heads — a 3-pack of self-sharpening SteelPrecision cutters designed to restore your Series 5000 (angular) and Series 7000 shaver to peak performance.

When shaving efficiency drops, worn cutting heads are usually the cause. The SH71/52 set brings back close, consistent cuts with 45 SteelPrecision blades crafted from high-grade Swedish steel and engineered in Europe. Each head contributes to fast cutting action and long-lasting sharpness so your electric razor can perform as intended without excessive tugging or missed hairs.

How do these replacement heads improve shaving performance?

Replacing worn heads renews blade alignment and gap tolerances, allowing the foil and cutters to shear hair cleanly. The self-sharpening SteelPrecision blades maintain an edge longer, producing steady cutting action across passes and reducing skin pulling.

• 45 high-performance blades per head for consistent cutting
• Self-sharpening design preserves edge over time
• Precision Swedish steel for durable sharpness
• Engineered in Europe to strict quality standards

Which shaver models are compatible with SH71/52 heads?

SH71/52 heads are intended for Philips Norelco angular-shaped Series 5000 (S5xxx) and all Series 7000 (S7xxx) models. They are not compatible with the rounded Series 5000 models, which require SH50 heads instead—always check your shaver model before ordering.

• Fits angular S5000 (S5xxx) shavers — not rounded S5000 models
• Compatible with all S7000 (S7xxx) Series devices
• Replaces former RQ12/70 and RQ12/60 part numbers
• Confirm model engraving on shaver underside or manual

How often should I change the shaving heads and what should I expect?

Philips Norelco recommends swapping cutting heads roughly every two years under typical use to keep cutting performance and skin comfort stable. With regular replacement, you can expect steady cutting action, reduced tugging, and improved shaving consistency compared to worn heads.

• Replace approximately every 24 months for average use
• Restores near-original cutting performance
• Helps maintain smooth passes and fewer re-strokes
• Three heads in the pack provide multiple future replacements

How do I install and care for the SH71/52 replacement heads?

Installation is straightforward: remove the old head assembly and snap the new triple-head unit into place following your shaver’s instructions. Clean after each use, rinse according to model guidance, and allow to dry between shaves to extend life and hygiene.

• Remove old head assembly before attaching new heads
• Rinse under water if your model allows, then air dry
• Inspect for hair buildup and clean regularly
• Store heads dry and replace according to usage

Who is this for: The SH71/52 3-pack is aimed at owners of angular Philips Norelco Series 5000 (S5xxx) and all Series 7000 (S7xxx) electric shavers who want genuine OEM parts to preserve performance and longevity. It suits users who prefer hassle-free swaps, value durable Swedish-steel cutters, and want a multi-pack to cover future replacements.
